얘 우리 딸 아니에요!

Sinopse

Sierra's peaceful village life is disrupted when her ex-boyfriend, Duke Cassius Ideos, shows up and mistakes the child she's raising as his daughter. The thing is, the girl is her niece, not her kid! When he refuses to listen to any explanation, her only option is to follow him to his duchy and await the results of a paternity test. All Sierra has to do is keep to herself for three months, but will things remain that simple when she begins to suspect that the duke still has feelings for her?
